选择１９８８年５月～１９９６年８月经头颅ＣＴ证实为单侧脑卒中且病灶波及语言相关区的病人１００例，在发病２周内进行失语检查，要求患者接受检查时神志清楚，定向力及记忆力好，无智能障碍，既往无脑部疾病史。其检测结果：左脑病变８０例中，有６６例失语；右脑病变２０例中，仅４例失语。经统计学处理差别有高度显著性。说明中国人左脑和右脑均可能控制语言，语言优势侧多在左侧。同时发现，右利手中，６８例左脑病变者有５８例失语，１７例右脑病变仅４例失语；非右利手中，１２例左脑病变者８例出现了失语，而３例右脑病变者均无失语。经统计学处理差别有显著性，说明中国人右利手者语言优势侧多为左半球，仅少数为右半球。非右利手者语言的控制仍以左半球为优势侧可能性大，至于有无双侧支配，尚待进一步研究证实。
100 patients who were confirmed as unilateral stroke by skull computed tomography from May 1988 to August 1996 and affected the language-related area were examined for aphasia within 2 weeks after onset, and the patients were required to have clear consciousness, orientation and memory during examination Good, no mental retardation, no prior history of brain disease. The test results: 80 cases of left brain lesions, 66 cases of aphasia; right brain lesions in 20 cases, only 4 cases of aphasia. The statistical difference was highly significant. This shows that the Chinese people may control the language of the left and right brains in the left and right sides, respectively. Right hand, right hand, 68 cases of left brain lesions in 58 cases of aphasia, 17 cases of right brain lesions only 4 cases of aphasia; non-Right-handed hands, 12 cases of left brain lesions in 8 cases of aphasia appeared, and 3 cases of right brain Lesions were no aphasia. The statistical difference was significant, indicating that the right-hand man of Chinese language mostly dominated the left hemisphere, only a small number of the right hemisphere. The control of non-right-winger languages is still likely to be dominated by the left hemisphere. As for whether or not there is bilateral control, further studies are needed to confirm this.
